Package: apt Version: 1.2 Severity: normal File: /usr/bin/apt-get Dear Maintainer,
Like the title says 'apt-get build-dep' does not retrieve the dependencies if the binary package is a NMU upload. For example, consider mlterm: apt-cache policy mlterm mlterm: Installed: (none) Candidate: 3.5.0-1+b1 Version table: 3.5.0-1+b1 990 990 http://ftp.debian.org/debian stretch/main amd64 Packages -10 http://ftp.debian.org/debian sid/main amd64 Packages Now, try to get its build deps: sudo apt-get build-dep mlterm Reading package lists... Done Building dependency tree Reading state information... Done E: Can not find version '3.5.0-1+b1' of package 'mlterm' E: Unable to find a source package for mlterm The same error persists even when I explicitly specify the version (sudo apt-get build-dep mlterm=3.5.0-1+b1) -- Package-specific info: -- /etc/apt/apt.conf: APT::Default-Release "stretch"; APT::Install-Recommends "0"; APT::Install-Suggests "0"; APT::Get::AutomaticRemove "1"; APT::Get::Build-Dep-Automatic "1"; -- /etc/apt/sources.list: deb http://ftp.debian.org/debian stretch main contrib non-free deb-src http://ftp.debian.org/debian stretch main contrib non-free deb http://security.debian.org/ stretch/updates main contrib non-free deb-src http://security.debian.org/ stretch/updates main contrib non-free deb http://ftp.debian.org/debian stretch-updates main contrib non-free deb-src http://ftp.debian.org/debian stretch-updates main contrib non-free deb-src http://ftp.debian.org/debian/ sid main -- System Information: Debian Release: stretch/sid APT prefers testing APT policy: (990, 'testing') Architecture: amd64 (x86_64) Kernel: Linux 4.3.0-1-amd64 (SMP w/4 CPU cores) Locale: LANG=en_IN, LC_CTYPE=en_IN (charmap=UTF-8) Shell: /bin/sh linked to /bin/dash Init: systemd (via /run/systemd/system) Versions of packages apt depends on: ii adduser 3.113+nmu3 ii debian-archive-keyring 2014.3 ii gnupg 1.4.20-1 ii gnupg2 2.0.28-3 ii gpgv 1.4.20-1 ii libapt-pkg5.0 1.2 ii libc6 2.21-6 ii libgcc1 1:5.3.1-5 ii libstdc++6 5.3.1-5 apt recommends no packages.
